While evidence suggests that transcranial direct current stimulation (tDCS) may facilitate language recovery in chronic post-stroke aphasia, individual variability in patient response to different patterns of stimulation remains largely unexplored. We sought to characterize this variability among chronic aphasic individuals, and to explore whether repeated(More)
Spondylothoracic dysostosis (STD), also known as Jarcho-Levin syndrome (JLS), is an autosomal-recessive disorder characterized by abnormal vertebral segmentation and defects affecting spine formation, with complete bilateral fusion of the ribs at the costovertebral junction producing a "crab-like" configuration of the thorax. The shortened spine and trunk(More)
BACKGROUND Treatment options for neuromyelitis optica (NMO) are currently based on small retrospective case series and open label studies, ranging from 10 to 103 patients. OBJECTIVE To compare the efficacy and tolerability of azathioprine, cyclophosphamide, mycophenolate, and rituximab in patients with neuromyelitis optica. METHODS This is a(More)
In the current study we describe the cases of 2 patients operated on for left-sided endocarditis, who later had myocardial ischemia develop secondary to left coronary artery compression from a pseudoaneurysm of the mitral-aortic fibrosa. Because the symptoms of angina persisted despite medical treatment, both patients had second surgeries. Myocardial(More)
BACKGROUND AND PURPOSE The utility and safety of brain biopsy for suspected primary angiitis of the central nervous system (PACNS) are uncertain. Factors predictive of a positive biopsy have not been well described. Our aim was to evaluate the diagnostic yield and safety of brain biopsy in suspected PACNS and determine whether any prebiopsy variables are(More)
INTRODUCTION Cystic tumors of the pancreas comprise 1% of all neoplasms of the pancreas and 10 to 15% of pancreatic cysts. There are a variety of cystic lesions, of which 90% is made up of serous cystadenomas, mucinous cystic neoplasms, intraductal mucinous neoplasms and solid pseudopapillary neoplasms. MATERIALS AND METHODS This study describes and(More)
Cord sera were obtained from term, Chilean newborns exhibiting various patterns of intrauterine growth and assayed for IGF-1, IGF-2, IGFBP-1, IGFBP-2, and IGFBP-3 by specific radioimmunoassays (RIA). Serum levels of each peptide were correlated with birth weight (BW), ponderal index (PI), and placental weight (PW). Total IGF-1 levels correlated with BW (r =(More)
Aphasia is a common result of stroke, affecting over one million Americans. Currently, intensive speech therapy is the mainstay of treatment, although its efficacy has been variable at best. Recent years have seen the emergence of non-invasive brain stimulation, specifically Transcranial Magnetic Stimulation (TMS) and Transcranial Direct Current Stimulation(More)
We describe the case of an intrapericardial pheochromocytoma located in the anterior surface of the heart and spreading over the pulmonary trunk. Under cardiopulmonary bypass (CPB) the tumor was removed. "En bloc" resection of the anterior wall of the right ventricular infundibulum and the pulmonary trunk was performed, with implantation of a fresh aortic(More)
